Ever notice that garlic’s stem resembles the windpipe? Some 15th-16th century physicians believed that plants showed their healing qualities within their physical form. Holding to that theory, it is believed that garlic nourishes the lungs and respiratory tract. It also helps the body dissolve arterial plaque, sustain heart health, and support the immune system. Garlic has truly earned the right to be one of the seven healers of the world.
